Mixed Reality Depth Occlusion Cues for Virtual Object Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixed reality devices struggle to accurately depict the positional relationship between real and virtual objects, leading to potential confusion and safety hazards for users.
Innovation Solution
A mixed reality device that determines the overlap between real and virtual objects by adjusting the appearance or position of virtual objects based on their relative positions, using a processing device to analyze depth images and adjust display accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If virtual objects are displayed overlaid on real space without considering depth information, then the display is simple and fast, but users cannot accurately grasp the positional relationship between real and virtual objects
Solution Approach 1:
The patent applies color changes to distinguish virtual objects based on their depth position. Virtual objects on the far side of real objects are displayed with different colors (e.g., transparent or outlined) compared to those on the near side, enabling users to quickly perceive depth relationships without complex processing
Solution Approach 2:
The patent adds depth information as a new dimension to the traditional 2D overlay display. By incorporating depth data from depth cameras and adjusting virtual object properties based on their distance from the user, the system creates a three-dimensional perception that accurately represents spatial relationships
2Reliability
If virtual objects on the far side are displayed with the same appearance as near objects, then the display is consistent and simple, but users may confuse virtual objects with real objects or misjudge distances
Solution Approach 1:
The patent uses color changes to indicate depth position. Virtual objects on the far side are displayed with distinct colors or transparency levels compared to near objects, making depth information visually apparent and improving user understanding without requiring complex interface elements
Solution Approach 2:
The patent introduces asymmetry in the display appearance based on depth position. Instead of uniform treatment, virtual objects are differentiated by their spatial relationship with real objects, creating visual cues that break symmetry to convey depth information effectively

AI summary
According to one embodiment, a mixed reality device overlays, on a real space, and displays a virtual object in a virtual space. The mixed reality device is configured to obtain a position of an object in the real space and a position of the virtual object. The mixed reality device is configured to change an external appearance of the virtual object when the virtual object is positioned on a far side of the object relative to the mixed reality device and overlaps the object.
